How to Design an Animated House
The wonder material of bamboo continues to amaze us with its potential. From plywood, to salad bowls, to the ethereal structures of Kengo Kuma, this sustainable, structural grass seems to have endless possibilities. Now, Bamboo Living is sponsoring an international competition to design buildings out of bamboo. The competition is open to all students, architects, and designers, with the goal of raising awareness of the ecological benefits of using bamboo as both a material and a technology.
What is fabric forming?
This unique "Tree House" by Sandy Lawton of Arro Design, Vermont, USA, 2007, used fabric formed columns, walls, and floors.
Fabric formwork replaces conventional rigid forming materials such as plywood or steel panels with a thin, flexible sheet of fabric When concrete is contained by a thin fabric membrane, the flexibility of the container naturally produces a set of beautiful and structurally useful tension geometries.In above-ground structures, fabric formwork is used to form:
In surface and marine applications, fabric formwork is used for:
Advantages of fabric forming
- Material Reduction: Fabric forms use hundreds of times less material than conventional rigid formwork. Concrete and steel can also be conserved by forming more efficient curved geometries.
- Cost Savings: Fabric forms cost far less than rigid forms due to the efficiency of the tensile-only membrane. In addition, certain fabrics can be reused many times over.
- Improved Concrete Quality: Permeable fabrics improve surface finish, compression, strength and impermeability by filtering air bubbles and excess mix water from the wet concrete.
- Waterproof Concrete: Inexpensive plastic-coated fabric forms provide a permanent waterproof shield when left on a concrete cast - useful, for example, in damp-proofing foundation footings.
- Beauty: Fabric-cast concrete is distinguished by its soft curves and immaculately detailed surfaces, offering unique forms of architectural beauty to concrete products and construction.
